Nancy Sinatra and Lee Hazelwood- Summer Wine.
I caught part of the song on R2 last night (Stuart Maconie I think) so I looked on Youtube and I've played it several times since.
I'm going to try to find the CD at the weekend.
Plus, I've also listened to "Some Velvet Morning" and Siw Malmkvist duetting with Lee Hazelwood.
Don't you just love Youtube ?
